CGRS  |  Iota Helium Leak Detection


     The Advantages
Closed system which prevents vapor loss during calibration.
Identify and resolve meter system equipment failures.
The Master Meter is not affected by in-field conditions.
Real time flow rate, gross volume and temperature are monitored during the run.
Fast and/or slow runs can easily be done with any gross volume well in excess of 5 gallons.
  Product density is monitored continually. If vapor, water or another foreign substance is present it is immediately detected and an error message will occur and the run will be terminated.
Measurement repeatability is between 0.02% and 0.03% of volume measured or about 1/20th of the required calibration differential standard of 0.5%.
This excellent repeatability is consistent regardless of the atmospheric conditions of in-field evaluations.
Safety – closed system minimizes exposure to vapors.
Accountability – the inspection and calibration results are automatically recorded and documented to ensure that the technician has met and/or exceeded the required standards.
More accurate, consistent inventory reconciliation.
  BACKGROUND

Since the early 1900’s, retail petroleum dispensing meters have been calibrated using volumetric proving technology — a 5 gallon open neck prover. This technology has been effective for many years, but with substantial volume increases in retail sales, the improved accuracy of dispenser meters and the high cost of fuel, the need for accurate calibration has become more critical than ever in order to promote fair trade. Electronic Proving Technology from MeterCal is today’s solution!

  HOW IT WORKS 

The EPT (MeterCal) system uses an extremely high quality, linearized Master Meter in series with the meter under test. The fuel nozzle is removed and the hose is plugged directly into the inlet on the master meter. The discharge hose on the outlet side of the Master Meter returns to the tank creating a closed loop system which allows fuel to be circulated through both meters in order to allow temperature equilibration between both meters. Once the meters have equilibrated, multiple slow and fast runs of any amount are performed and automatically captured by the onboard computer. Meter error and fast to slow ratio are automatically calculated and documented. The meter is adjusted as needed and the process is repeated until it is as close to zero as possible.
